Prior to mass production of vinyl, test pressings are done to ensure that the record turns out as it should. They are rare to come across, and our featured eBay item certainly fits the bill: a test press of Green Day's first full album, 39/Smooth.

Test pressings of early Green Day records have sold for over $1,000 in the past...and this one has only been bid to $82 so far, though the reserve price hasn't been met. Most collectors don't even have test pressings like this. If you're a collector, bid on it while you have the chance!
